Ultrasonic Phased Array Inspection Technology Researchof PE Gas Pipeline Welding Seam

In view of the detection frequency, depth of focus, wafer size and the number of wafers of the phased array ultrasonic testing probe will affect the detection sensitivity, the PE pipe butt weld test was investigated, and wave3000 software was adopted to measure the ultrasonic phased array probe parameter optimization design, and the reliability of the simulation analysis in experimental form was verified. Ultrasonic phased array technology was used to detect the known defects. A calibration block similar to the speed of sound of PE material was designed to verify the accuracy of experimental data. The results show that a calibration block is used to calibrate the instrument to detect defects in PE pipe quickly and accurately.
